摘　　要：为了提高深海压力筒的模拟精度,基于液体的可压缩性提出了一种可以测量微小水压变化的双液压缸式深海压力筒的设计方案。介绍了该方案的工作参数及系统组成,分析了压力筒的变形情况,分别建立了不考虑压力筒变形时活塞进给量与压力的数学模型及考虑压力筒变形时活塞进给量与压力的数学模型,并利用origin软件做出了其关系曲线。结果表明:利用压力筒模拟海下环境时,不仅应考虑液体压缩对压力的影响,同时还需考虑压力筒变形对压力的反向影响。In order to improve the simulation accuracy of deep-sea pressure cylinder,based on the compressibility of liquid,a design scheme of doublehydraulic cylinder deep-sea pressure cylinder which can measure the small change of water pressure is proposed.The working parameters and system compositions of the scheme are introduced.The deformation of pressure cylinder is analyzed.The mathematical model of piston feed rate and pressure without cylinder deformation and the mathematical model of piston feed rate and pressure with cylinder deformation are established to make its relation curve in origin software respectively.The results show that not only the effect of liquid compression on pressure,but also the reverse effect of cylinder deformation on pressure should be considered when using pressure cylinder to simulate underwater environment.
